But everything is not so simple, because many children, adults and even animals fall into a coma or even die as a result of overheating of the head. If you don't believe me, try searching the Internet for information on sunstroke victims. You will most likely be horrified by the search results.

What happens during a sunstroke?

In a professional environment, sunstroke is called heliosis. As can be understood, it arises as a resultexcessive heating of the head under the sun. First of all, the skin suffers from the sun's rays, and then it transfers heat to the cerebral cortex. As a result of this, the blood vessels of a person expand and a powerful flow of blood goes to the head. It can “stagnate” there and lead to rupture of small vessels - this directly threatens the health of the human central nervous system.

Hot sun is just as bad as freezing winter

Also, the sun's rays cause changes in tissueprotein, the breakdown of leukocytes and young skin epithelium. Because of this, a lot of decay products enter the body. The human body becomes unable to independently regulate body temperature through sweating and so on. The result is heat stroke.

Interesting fact: Women need warmth more than men. Here is the explanation.

Sunstroke symptoms

Sunstroke can be of varying degrees - it all depends on how long the person has been under the scorching sun.

Here are the most common symptoms of sunstroke, depending on the severity:

  • mild sunstroke manifested by weakness, headache, nausea, increased breathing and heart rate, as well as dilated pupils;
  • moderate sunstroke includes all the previous symptoms but, in addition to them, there is a feeling of stupor, staggering gait, fainting and body temperature in the region of 38-40 degrees;
  • sunstroke of the highest degree appears suddenly:a person's skin becomes pale, confusion, hallucinations, convulsions, involuntary excretion of feces and urine occur, and body temperature can rise to 42 degrees.

In the absence of medical care, severe casessunstroke in 20-30% ends with the death of a person. First aid is to move the person into the shade and apply a cold compress to the head. In this case, you need to immediately call an ambulance.

What is heat stroke?

Sunstroke and heatstroke are not the samephenomena. Heat stroke is a condition that occurs when the body overheats above 36.6 degrees. Sunstroke is a specific type of heat stroke. Heatstroke is much easier to get than sunstroke - it is enough to work in an excessively warm and stuffy room or walk in too thick clothes.

Heatstroke hits a person faster than sunstroke

Heat stroke symptoms:

  • skin redness;
  • weakness in the whole body;
  • nausea and vomiting;
  • dizziness;
  • muscle spasms.

In case of heat stroke, a person should be put ona flat surface - if there is vomiting, you need to make sure that the victim does not choke. In addition to cold compresses, you can douse a person with cool water up to 20 degrees Celsius. Of course, you need to immediately call an ambulance, because only specialists can provide full support.

Global warming could deprive people of sleep. That's why.

How to protect yourself from sunstroke

To prevent overheating of the body,it is necessary to walk in the heat in light-colored clothes and drink plenty of water. During work, it is necessary to take breaks more often, and on a particularly hot afternoon, you need to arrange a siesta - this is the name of the time when during the hot part of the day people sit in shelter and rest. In the heat, you can not eat too much food, and even more so do not drink alcoholic beverages.

On hot days, you need to try to get more rest.
